Need a jolt from those hours spent running on your treadmill or pedaling on that stationary bicycle? The folks at Shadowbox have just the answer. A 45-minute class here will have you channelling your inner “Ali”. High energy music gets you in the groove for intense shadowboxing, interval training and body weight exercises (as in those dreaded but oh-so-effective planks), making this a terrific yet grueling full body workout. Put up your dukes!
